Overview

With conventional monitoring and communication system for a controlled environment, it is sometimes difficult for a control center of the controlled center to effectively communicate with and monitor staff/guards (hereinafter “personnel”) during an assignment. Also, it is sometimes difficult for personnel to effectively detect potential danger and protect themselves. As a result, personnel is in danger, and importation of contraband goods occurs. Meanwhile, smart devices utilized in a controlled environment allow personnel to stay in constant contact with the control center of the controlled environment. The use of these devices would offer many other features and functions that would prove beneficial to the personnel and jurisdictions.

The present disclosure provides details of a system and method for a communication device for guards in a controlled environment. The communication device is established based on a wireless infrastructure in the controlled environment, receiving wireless positioning signals to calculate and determine the real-time location of personnel carrying the device. The indoor wireless positioning can be combined with other available positioning methods, e.g., GPS positioning, to provide highly accurate positioning information of the personnel. The communication device detects and records activities of the personnel during a period of time, and is controlled by the control center. The status of personnel is monitored by control center. Meanwhile, the communication device has AR functions that allow physical objects and augmented reality element to be displayed to the personnel at the same time. The personnel can thus have improved awareness of the surrounding environment and can respond to various potential dangers more effectively. The control center and the communication device respond quickly to different situations. In addition, the communication device detects contraband electronic devices, items out of place, and inmates in forbidden locations, and monitors surroundings of the personnel in real-time. Third party can also monitor real-time of the personnel and the surrounding environment in real-time. Thus, the disclosed system and method for the communication device provides improved communication and monitoring for personnel in a controlled environment.

Control center 102 has the option to store, process, and/or display these data. In some embodiments, control center 102 controls the content of information displayed by visualization unit 112. In some embodiments, control center 102 obtains data from database 113 or receives input from a user of control center 102 and sends the data to the personnel carrying multi-functional platform 101. The data is processed and/or displayed in visualization unit 112. In some embodiments, control center 102 joins images and/or videos recorded by different units to a desired format, e.g., a wide-angle landscape-style image/video formed by a plurality of images/videos taken from different angles, and displays the joined image/video to the personnel. In some embodiments, control center 102 is installed with software and hardware that control the operations of different units of multi-functional platform 102. In some embodiments, commands from control center 102 override commands from the monitored personnel.

Control center 102 also monitors the activities of the monitored personnel carrying multi-functional platform 102. In various embodiments, control center 102 monitors and displays the path, moving speed, dwelling time, body motion, and/or heart rate of a guard. In an embodiment, control center 102 is installed with software for remotely controlling the parts and functions multi-functional platform 101. For example, a monitoring personnel of control center 102 turns on and off certain units, e.g., the monitoring unit 109 of multi-functional platform 101, at a desired time. In an embodiment, control center 102 includes hardware and software for facilitating communication between the monitored personnel in the control environment and monitoring user at control center 102, and control center 102 monitors the communication in real-time. For example, control center 102 includes and a messaging program for the monitoring personnel and the monitored personnel to communicate in type-in messages or voice messages. In an embodiment, control center 102 includes software and hardware for receiving and playing audio/video data from multi-functional platform 101. For example, in an embodiment, control center 102 includes a speaker and a microphone so that personnel using multi-functional platform 101 and the monitoring personnel of control center 102 can have real-time conversations. In case of an abnormal activity received from multi-functional platform 101, control center 102 plays an alert through the speaker. The alert includes any suitable pre-recorded messages for attracting the attention of the audience. In various embodiments, control center 102 is installed with software for recording various information of each monitored personnel. For example, control center 102 records moving path, moving speed, dwelling time, body motion, heart rate, conversations, messages, and/or recorded images/videos associated with each monitored personnel. In various embodiments, control center 102 has the authority to monitor any information forwarded by information relay unit 103. In another example, control center 102 allows the monitoring personnel to access the real-time video streaming and/or observes views observed by the monitored personnel. Other communication means can also be used at the same time such that the monitored user and the monitored personnel observe, communicate, and respond to situations in the surroundings at the same time.

In various embodiments, abnormal activities that trigger responses of control center 102 include the path of the monitored personnel deviating from a designed path, monitored personnel not responding to an inquiry within a certain period of time, monitored personnel having a sudden body motion, monitored personnel having a sudden heart rate increase, monitored personnel failing to complete an assignment within a certain period of time, monitored personnel sending an alert, detection of contraband wireless signals, detection of abnormal presence of inmates, items out of place or in abnormal conditions, etc.

In an embodiment, database 113 stores any suitable data that can be used for the communication and monitoring functions of control center 102. For example, database 113 stores biometric data, identification data, and profile data of the monitoring personnel, monitored personnel, and/or inmates, offense history and reasons for incarceration of inmates, contact history, distribution information of multi-functional wireless devices used by inmates, a map of the control environment, designed paths for the monitored personnel, coordinates of certain locations and objects, reference data for positioning, criteria for determining “abnormal” and “normal” status/activities/actions, conversation history and messages associated with the monitored personnel, etc. For example, biometric data includes voice samples, fingerprints, retina samples, and/or facial structures associated with a monitored or monitoring personnel; identification data includes biometric data, name, birthday, social security number (SSN), and/or PIN number associated with a monitored or monitoring personnel; profile data includes identification data, offense history, contact history, reason of incarceration, cell number, and/or assigned multi-functional wireless device. The map of the control environment includes coordinates of the boundaries of cells, areas, walls, and/or names and restrictions of each cell/area. Designated paths for monitored personnel define, e.g., areas, paths, dwelling times, assignment completion time, and/or moving directions a monitored personnel is expected to follow in an assignment. Reference data for determining the location or proximity includes, e.g., coordinates of positioning signal transmitters and positioning signal strength in the proximity of the signal transmitters. Criteria for determining which status are “normal” includes a set of ranges in, e.g., time, distance, location, path, moving speed, and body condition, during an assignment or a certain period of time, for limiting the activities of the monitored personnel. “Abnormal” status refers to these status failing to satisfy the criteria. For example, it is determined the monitored personnel following the designed path being “normal,” and a deviation from the designed path is determined to be “abnormal.” Conversation history and messages associated with a monitored personnel include the conversation history and messages recorded during an assignment in the control environment. In various embodiments, control center 102 also includes a display unit for displaying status of one or more monitored personnel, a user input device for receiving commands/selections from a monitoring personnel, etc.

In an embodiment, control center 102 simulates real-time activities of a monitored personnel based on data stored in database 113 and signals/data sent by multi-functional platform 101. Control center 102 uses the data to generate graphics, images, and/or text based on the received and stored data. For example, control center 102 extracts coordinates information from database 113 to generate a map of the controlled environment, simulate/calculate the path, moving speed, and/or dwelling times of the monitored personnel in the map based on the real-time data received by multi-functional platform 101. A monitoring personnel then directly observes and monitor the activity of a monitored personnel. In various embodiments, control center 102 also simulates other detectable objects/subjects in real-time in the map. For example, based on data/signals sent by multi-functional platform 101, control center 102 also simulates the presence and status of inmates wearing/carrying certain signal-transmitting tags, e.g., radio frequency (RF) ID tags, and/or any devices transmitting a suitable detectable signal, e.g., a kiosk, a contraband device, and/or a vending machine. The detectable objects/subjects are also displayed in the map to the monitoring personnel. In an embodiment, control center 102 also sends calculated path, moving speed and path to respond based on the activities. For example, control center 102 determines whether any abnormal activities occurred based on the calculation result, and/or respond accordingly based on the abnormal activities. In an embodiment, control center 102 displays certain simulation results in the form of graphics, images, sound, and/or text, to the monitored personnel and/or the monitoring personnel. In an embodiment, the simulation results are displayed by visualization unit 112.

In an embodiment, control center 102 responds to data/signals sent by multi-functional platform 101. Control center 102 is programmed to respond to different inquiries from multi-functional platform 101 and extract necessary data from database 113 for the responses. Control center 102 directly responds to some signals/data, e.g., emergency calls/alerts. A monitoring personnel has the option to manually interrupt and respond to some signals/data through control center 102. In some embodiments, a monitoring personnel is required to authenticate his/her identity before interrupting the operations of control center 102. Decisions made by control center 102 are transmitted to information relay unit 103 through connection link 114 and implemented in designated units of multi-functional platform 101. In various embodiments, control center 102 responds to inquiries such as detection of abnormal activities of the monitored personnel, detection of contraband wireless signals, detection of items out of place, and/or messages/alerts/video streams/images sent by the monitored personnel. Response of control center 102 to the inquiries includes starting certain monitoring functions of multi-functional platform 101, sending alerts/alerts to one or more monitored personnel, etc. In some embodiments, control center 102 records the activities during a certain period of time or assignment and analyze the recorded history if necessary. For example, conversation or messages of a monitored personnel can be recorded, parsed, and/or analyzed.

In some embodiments, control center 102 includes suitable hardware and software for performing virtual reality (VR) functions. For example, control center 102 utilizes real-time data and/or non-real-time data to construct a virtual reality (VR) space for the monitoring personnel. The real-time data and non-real-time data can be any suitable data received by control center 102. For example, these data can include real-time video streaming data and recorded non-real-time video data captured by any suitable imaging devices, e.g., cameras, of multi-functional platform 101. These data can also include positioning data, facial recognition data, audio data, AR data, etc. When using real-time video streaming data to construct a VR space, control center 102 simulates the surroundings of the monitored personnel based on real-time data such as the real-time video data, real-time audio data, and positioning data of the monitored personnel to present the surroundings of the monitored personnel in a VR space. When using non-real-time data to construct a VR space, control center 102 simulates the surroundings of the monitored personnel based on non-real-time data such as recorded video data, recorded audio data, and recorded positioning data of the monitored personnel to present the surroundings of the monitored personnel in a VR space. In some embodiments, the monitoring personnel has the option to choose real-time/non-real-time data streamed/recorded from one or more desired imaging devices to construct the VR space. The monitoring personnel thus has the option to observe the surroundings of the monitored personnel in a VR space in a real-time session or in a previously recorded. In some embodiments, control center 102 further includes VR devices, e.g., headsets, helmets, goggles, etc., worn by the monitoring personnel to enhance VR effects.

Control center 102 is bi-directionally connected to multi-functional platform 101 through connection link 114. Connection link 114 includes any suitable wired (e.g., Ethernet) connection or wireless connection. The wireless connection can be implemented as one or more of a wide-area network (WAN) connection, a local area network (LAN) connection, the Internet, a Bluetooth connection, and/or an infrared connection. Other types of implementations for a wired or wireless connection are possible without deviating from the scope of the present disclosure. Control center 102 has the authority to control the functioning of various units in multi-functional platform 101.

Information relay unit 103 is bi-directionally connected to control center 102. Information relay unit 103 includes hardware and software to receive various data/signals from other units in the multi-functional platform 101 and forward the received data/signal to control center 102, and receive signals/data from control center 102 and distribute the signals/data to proper units. In some embodiments, information relay unit 103 is configured to determine the proper data to be sent to control center 102. For example, when positioning unit 105 sends both indoor and outdoor tracking or positioning information to information relay unit 103, information relay unit 103 determines the appropriate positioning information to be forwarded to control center 102 based on the actual location of the monitored personnel. In an example, information relay unit 103 determines the actual location of the monitored personnel based on the received tracking information from positioning unit 105 and sends the positioning information that more precisely reflects the actual position/status of the monitored personnel. In an example, when information relay unit 103 determines the monitored personnel is located in the indoor environment of the control environment, information relay unit 103 only sends the indoor positioning information to control center 102; when information relay unit 103 determines the monitored personnel is located in the outdoor environment of the control environment, information relay unit 103 only sends the outdoor positioning information to control center 102. In some embodiments, information relay unit 103 sends both indoor positioning information and outdoor positioning information sent by positioning unit 105 to control center 102. In various embodiments, information relay unit 103 encrypts information sent to control center 102 and decrypts information sent by control center 102.

Messaging unit 104 is bi-directionally connected to control center 102 and includes software and hardware to facilitate texting/messaging functions between the monitored personnel and control center 102. In an embodiment, the messages transmitted between multi-functional platform 101 and control center 102 are in various forms such as text messages, videos, images, audio messages, and/or real-time video streams. The monitored personnel has the option to enter desired text and/or audio, take pictures and/or record videos, or stream videos. The various forms of messages are sent to control center 102 through information relay unit 103. In an embodiment, messaging unit 104 also enables texting/messaging functions among different monitored personnel. A monitored personnel has the option to select a desired recipient and the various forms of messages are redirected to the selected recipient by control center 102. A monitoring personnel at control center 102 has the authority to monitor any messages forwarded by information relay unit 103.

Positioning unit 105 tracks both the indoor position and the outdoor position of the monitored personnel. Positioning unit 105 is bi-directionally connected to control center 102 through information relay unit 103 and includes software and hardware to enable the positioning of the monitored personnel when the monitored personnel is in the indoor or outdoor environment of the control environment, where positioning signals are available. In some embodiments, positioning unit 105 includes an outdoor positioning sub-unit. In an embodiment, the outdoor positioning sub-unit includes a global positioning system (GPS) receiver. In some other embodiments, other GPS-based positioning means or other positioning systems are also used alone or in combination with GPS. The outdoor positioning sub-unit determines the locations of one or more monitored personnel in real-time. The outdoor positioning sub-unit periodically sends coordinates of the monitored personnel to information relay unit 103, and information relay unit 103 determines whether the coordinates are to be sent to control center 102.

In some embodiments, positioning unit 105 also includes an indoor positioning sub-unit. The indoor positioning sub-unit periodically sends location-reflecting signals/data to information relay unit 103. In an embodiment, the indoor positioning sub-unit includes one or more of any suitable wireless positioning facilities such as radio frequency (RF)-based positioning systems, Bluetooth-based positioning systems, WiFi-based positioning systems, and/or ultrasound-based positioning systems. For example, the RF-based positioning system includes a RFID reader and a plurality of RFID tags/beacons distributed in the indoor environment. The RFID reader, carried by the monitored personnel, reads information stored in the nearby RFID tags and sends the read-out information to information relay unit 103. In another example, the WiFi-based positioning system includes a WiFi-signal reader and a plurality of access points. The WiFi-signal reader receives WiFi signals from access points and sends the detected WiFi signals to information relay unit 103. In another example, a Bluetooth-based positioning system includes a Bluetooth-signal reader and a plurality of Bluetooth beacons. The Bluetooth-signal reader receives the Bluetooth signals and sends the detected Bluetooth signals to information relay unit 103.

In an embodiment, information relay unit 103, based on received signals/data from the outdoor positioning sub-unit and the indoor positioning sub-unit, determines which signals/data are to be sent to control center 102. For example, when signals/data sent by the outdoor positioning sub-unit are weak or not available, information relay unit 103 determines the monitored personnel is in an indoor environment of the controlled environment and sends the signal/data from the outdoor positioning sub-unit to control center 102; when signals/data sent by the indoor positioning sub-unit are weak or not available, information relay unit 103 determines the monitored personnel is in an outdoor environment of the controlled environment and sends the signal/data from the indoor positioning sub-unit to control center 102. Information relay unit 103 has the ability to determine which signals/data are to be sent to control center 102 based on certain criteria, e.g., signal strength and signal availability. In some other embodiments, information relay unit 103 sends signals/data from both outdoor positioning sub-unit and indoor positioning sub-unit to control center 102. In some embodiments, information relay unit 103 switches between an “outdoor mode” and an “indoor mode”, based on the received signals/data. In the outdoor mode, only the outdoor tracking function is available, and in the indoor mode, only the indoor tracking function is available.

After control center 102 receives the tracking signals/data from information relay unit 103, control center 102 simulates the location/position of the monitored personnel in the map of the controlled environment based on the received signals/data. Because control center 102 periodically receives real-time tracking signals/data, the simulation reflects the real-time status, e.g., path, location, movement, and/or dwelling time of the monitored personnel. Control center 102 has the option to utilize certain reference data stored in database 113 to calculate the location of the monitored subject. For example, when the monitored subject is in an indoor environment, control center 102 determines the location of a monitored personnel based on reference signal strength data and signal attenuation information. Control center 102 also includes suitable algorithm or model stored in database 113 to detect whether the status of the monitored personnel is abnormal, e.g., monitored personnel deviating from designed path, monitored personnel staying at a certain location for an abnormally long time, monitored personnel having a sudden body motion, and so on. In some embodiments, control center 102 responds to an abnormal status by triggering an alert or other actions.

Contraband signal detection unit 106 is bi-directionally connected to control center 102 through information relay unit 103 and includes hardware and software to detect unknown or forbidden wireless signals. Contraband signal detection unit 106 is configured to detect any wireless signals, e.g., WiFi hot spots, Bluetooth signals, and/or RF signals, not recognized or forbidden by multi-functional platform 101 or control center 102. For example, contraband signal detection unit 106 includes one or more wireless signal detectors that scan a wide range of signal frequencies, e.g., RF frequencies or cellular frequencies, to detect any unknown or forbidden wireless signals. Contraband signal detection unit 106 sends frequencies of detected signals to information relay unit 103. In one embodiment, information relay unit 103 forwards the received detected wireless signals to control center 102, and control center 102 compares the detected wireless signals to known and permitted wireless signals to determine whether contraband wireless signals are contained in the detected wireless signals. If a contraband wireless signal is detected, control center 102 sends a message or an alert to inform the monitored personnel a contraband frequency has been detected and prompts the monitored personnel to search for the contraband device.

Alert unit 107 is bi-directionally connected to control center 102 and includes software and hardware for alerting the monitored personnel or control center 102. In an embodiment, a monitored personnel has the option to trigger alert unit 107 so that control center 102 receives an alert from the monitored personnel. In another embodiment, control center 102 triggers alert unit 107 so that one or more monitored personnel receive the alert. An alert can be in the form of alarms, text messages, audio messages, etc.

Motion detection unit 108 is bi-directionally connected to control center 102 and includes software and hardware to detect sudden body motions of a monitored personnel and items that are out of place. In some embodiments, motion detection unit 108, including one or more motion sensors, sends a motion signal to control center 102 through information relay unit 103 when a sudden body motion of a monitored personnel is detected. Control center 102 sends a confirmation message to the monitored personnel. In an embodiment, if the monitored personnel responds to the confirmation message in a defined time period, the motion signal is disregarded; if the monitored personnel fails to respond to the confirmation message in the defined time period, control center 102 triggers other actions such as sending an alert to other monitored personnel informing the location of the monitored personnel failing to respond to the confirmation message. The confirmation message can be in the form of alert, text messages, audio messages, etc. In some embodiments, motion detection unit 108 also includes one or more motion detectors for detecting items not in their proper conditions. For example, motion detectors can detect doors, windows, and/or gates that are open but should be closed. The conditions of these items are recorded by multi-functional platform 101 and sent to control center 102 through information relay unit 103.

Monitoring unit 109 is bi-directionally connected to control center 102 and includes software and hardware to monitor activities of the monitored personnel. Monitoring unit 109 includes at least recording abilities, e.g., using cameras and/or microphones, to stream or record at a desired time.

In an embodiment, processor 302 also calculates/analyzes detected signals.

In some embodiments, processor 302 recognizes the types of detected signals based on the frequencies of the detected signals. If the signals are wireless positioning signals, processor 302 calculates the location/position of the monitored personnel based on certain parameters, e.g., strengths of signals, and reference data, stored in memory 309. Signal reader 308 detects positioning signals of one or more positioning methods, transmitted from different positioning signal transmitters 312 located at same or different nearby places. Processor 302 calculates the location under different positioning methods. In some embodiments, processor 302 has the option to select one location with the highest precision, or supplement different positioning methods using one another to obtain a corrected location. In an embodiment, processor 302 simulates the location of the monitored personnel and display 303 displays the real-time status, e.g., path, location, moving speed, and/or dwelling time in the map of the controlled environment. Processor 302 also responds accordingly based on the current status of the monitored personnel. For example, processor 302 determines whether abnormal activities have been detected and notifies the monitored personnel if abnormal activities have been detected. In an embodiment, processor 302 sends an alert to control center 102 when abnormal activities are detected.

If the detected signals contain wireless identification signals, processor 302 extracts identification information from the signals and determines the location or proximity of objects/subjects transmitting the identification signals based on current location and information contained in the identification signals. In an embodiment, processor 302 simulates the locations/proximities of the objects/subjects and display 303 displays the real-time status, e.g., locations/proximities and moving speed in the map of the controlled environment. Processor 302 also responds accordingly based on the current status of the detected objects/subjects. For example, processor 302 determines sending an alert to control center 102 when abnormal activities, e.g., objects/subjects being at forbidden locations/proximities, are detected.

If the detected signals contain wireless communication signals, processor 302 extracts unknown or forbidden communication signals from the detected signals. Based on the location and proximity information determined, processor 302 also determines the location/proximity of a contraband wireless communication signal and display the contraband wireless communication signal at the location/proximity it's detected, in the map. In an embodiment, processor 302 notifies the monitored personnel the detection of any contraband wireless communications and sends the detection result to control center 102.

In an embodiment, the detected signals contain wireless communication signals and/or wireless identification signals of multi-functional wireless devices that are assigned to inmates. These multi-functional wireless devices allow inmates to wirelessly communicate with personnel of the controlled environment and/or contacts outside of the controlled environment. The wireless signals of a multi-functional wireless device contains the location restriction information of the multi-functional wireless device. For example, the wireless signals can indicate the area the multi-functional wireless device is permitted to be positioned. If it is detected that the multi-functional wireless device is positioned at a forbidden location, processor 302 notifies the monitored personnel and/or control center 102 the detection of a forbidden multi-functional wireless device in a nearby area. In an example, a multi-functional wireless device, which is only allowed to be located in cell/room 2 and the public dining area, is detected to be in cell 4. Accordingly, processor 302 notifies the monitored personnel and/or control center 102 the multi-functional wireless device is violating the rules and is located in cell 4.

In another embodiment, when a multi-functional wireless device is detected to be at a forbidden area, the monitored personnel and/or control center 102 have the option to remotely activate the covert features of the multi-functional wireless device, e.g., automatically streaming certain data such as audio, video, location information, and current usage of the multi-functional wireless device, to portable device 301 and/or control center 102 without notifying the inmate using the multi-functional device. In some embodiments, the monitored personnel and/or control center 102 can activate the covert features of any detected multi-functional wireless device detected in the nearby areas.

Antenna 313 represents any suitable number of signal receivers necessary to detect the positioning signals.

In various embodiments, portable device 301 automatically switches from “indoor mode” to “outdoor mode” when GPS signals are sufficiently strong and positioning signals are weak, and vice versa. Control center 102 and/or monitored personnel also have the authority to select one or more positioning methods on the portable device 301. In some embodiments, control center 102 selects GPS positioning to be supplemented with other positioning methods to provide positioning information of desirable precision.

In various embodiments, portable device 301 periodically sends detected/sensed signals/data to control center 102 for analysis and updates. Accordingly, control center 102 determines the response to any inquiry from portable device 301. In some embodiments, portable device 301 analyzes and responds to certain signals/data without inquiring control center 102. In an example, portable device 301 stores the map of the controlled environment and simulates the current path, location, and/or moving speed of the monitored personnel in the map based on positioning data. When an abnormal activity is detected, an alert is sent to the monitored personnel and/or control center 102. Meanwhile, portable device 301 sends positioning data to control center 102 so that control center 102 updates and monitored current status of the monitored personnel.

In various embodiments, portable device 301 communicates with one or more of AR devices 211 to control the functions of these AR devices 211.

In some embodiments, AR headset 400 further includes a microphone 407 for receiving the monitored personnel's voice responses/instructions.

In some embodiments, front camera 403, e.g., an outward facing visible-light camera, captures a wide angle of the front view. In some embodiments, front camera 403 stays on during the assignment or is turned on by monitored personnel and/or control center 102 at any time during an assignment.

In some embodiments, AR headset 400 further includes a rear camera 406 (not showing in FIG. 4A), facing outward, for capturing a rear view of the monitored personnel. In some embodiments, rear camera 406 includes a short-wavelength infrared camera. In some embodiments, the infrared camera is turned on when infrared radiation (e.g., infrared radiation emitted by humans) is detected and starts recording the rear view in infrared images/videos. In some other embodiments, rear camera 406 includes an infrared sensor and a visible-light camera. When the infrared sensor detects infrared radiation, the visible-light camera starts recording images/videos. The monitored personnel, control center 102, and/or portable device 301 have the option to choose which camera to use, e.g., based on different assignments. Accordingly, AR headset 400 starts displaying real-time images/videos captured by the rear camera to the monitored personnel when infrared radiation is detected.

In some embodiments, AR headset 400 further includes one or more side cameras, facing outward. For example, AR headset 400 can include side cameras, e.g., 404 and 405, on the left and right sides of AR headset 400. For illustrative purposes, side camera 405 is shown on AR headset 400. Side cameras 404 and 405 can each be a visible-light camera or a short-wavelength infrared camera. The operation of side cameras 404 and 405 can be referred to the operation of front camera 403 and rear camera 406. In some embodiments, front camera 403, rear camera 406, and side cameras 404 and 405 together capture an angle of 360° around the monitored personnel so that the monitored personnel is able to monitor the entire surroundings at the same time.

In some embodiments, AR headset 400 includes real-time facial recognition functions. In some embodiments, when AR headset 400 detects a human's face in the images/videos, AR headset 400 captures the facial features of the detected object and compares the facial features with stored facial features or sends the facial features to portable device 301 and/or control center 102 for comparison. After the objected has been recognized, AR headset 400 further displays augmented reality element such as the identity and other related profile information of the object to the monitored personnel in real-time. For example, when the object is detected to be an inmate, AR headset 400 displays the profile data such as the name, inmate ID number, offense history, contact history, reason of incarceration, cell number of the inmate together with the real-time images/videos of the inmate. In some embodiments, when the object is detected to have significant offense history, e.g., felony or having violence history with guards, an augmented reality alert is displayed to the monitored guard. In some embodiments, the real-time facial recognition function is only applied on the rear view. In some embodiments, the real-time facial recognition function is applied on one or more of the front view, the rear view, and the side views, depending on the selection by the monitored personnel, control center 102, and/or portable device 301.

FIG. 4B illustrates a block diagram of processor 409 of AR headset 400, according to embodiments of the present disclosure.

Input/output 408 is bi-directionally connected to processing unit 410 and includes circuitry such as a microphone, keyboard, and cameras. One or more cameras, outward facing as illustrated in FIG. 4A, are utilized for capturing visual information regarding the physical environment being viewed by the monitored personnel. Information from these outward facing cameras is provided to processing unit 410. In some embodiments, AR headset 400 further includes one or more inward facing cameras, utilized to capture biometric information of the monitored personnel. Biometric information may be authenticated by AR headset 400, portable device 301, and/or control center 102. Input/output unit 310 may be used to enter or output, e.g., audio, images, video, and/or text.

Sensing module 419 is bi-directionally connected to processing unit 410. Sensing module 419 is configured to for detecting various patterns such as biometric features and items out of place. In an example, sensing module 419 utilizes inputs received from input/output 408 to authenticate the identity of the monitored personnel and/or to recognize items in abnormal conditions. In some embodiments, AR headset 400 is installed with pattern recognition functions, and sensing module 419 is configured to recognize items in abnormal conditions, e.g., doors/windows/gates that are open but should be closed. In an example, biometric sensors are used for authenticating the identity of the monitored personnel and/or identify inmates/other personnel. For example, an inmate's biometric samples can be recorded and sent to control center 102 for analysis and/or recording purposes.

In some embodiments, input/output 408 and/or sensing module 419 receives various types of inputs, e.g., eye movements, head movements, and type-ins, and converts these inputs to input signals to be sent to processing unit 410. In some embodiments, input/output 408 includes various sensors, e.g., motion sensors, for detecting movements of certain body parts of the monitored personnel such that processing unit 410 determines the response of AR headset 400 to the input. For example, eye movement of the monitored personnel can be monitored through an inward facing camera. Eye movement of the personnel can operate much like a mouse by following the eye movement moving a cursor and utilizing the blinks of the eyes to select an item (i.e., similar to a mouse click). This allows for the entry of alpha numeric or the selection of items from the display without the personnel having to use his fingers or hands. Input/output circuitry further includes a projector and other sensors for aligning the augmented reality element that is displayed as, for example, a graphical overlay, in relation to the physical real-world objects.

In some embodiments, AR headset 400 is capable of displaying an augmented reality input interface, according to embodiments of the present disclosure. In some embodiments, For example, as shown in FIG. 4C, AR headset 400 provides a virtual keyboard that is displayed as if it were on a detected surface. As shown in FIG. 4C, in an embodiment, AR headset 400 detects that the monitored personnel is looking at his arm 423 based on image recognition techniques performed at AR headset 400. Upon detecting arm 423, AR headset 400 determines that the monitored personnel would like an input device to interact with multi-functional platform 101 and displays augmented reality input interface 424 which is displayed by AR headset 400. Augmented reality input interfaces are another type of augmented reality element and can be similarly implemented as a graphical overlay over a physical real-world object. In some embodiments, augmented reality element 425 is configured to display a communication that the monitored personnel wishes to send such as an email.

Accordingly, augmented reality element 425 can concurrently display augmented reality input interface 424 on the monitored personnel's detected arm as well as augmented reality element 425. In this manner, the monitored personnel can utilize augmented reality input interface 424 to input text or otherwise interact with content displayed in augmented reality element 425. The monitored personnel may utilize another input device to interact with augmented reality input interface 424. As one example, the monitored personnel may use his/her hand 426 to point to specific points of augmented reality input interface 424 to select letters to input into augmented reality element 425. Other means to interact with augmented input interface 424 include voice commands. For example, the personnel says “A.” Accordingly, AR headset 400 records the voice command and recognizes it as an input for augmented input interface 424. AR headset 400 then selects “A” and displays it on augmented reality element 425. In some embodiments, the input is sent to one or more of AR headset 400, portable device 301, and control center 102.

In some embodiments, similar to portable device 301, AR headset 400 is able to detect nearby multi-functional wireless devices and stream certain files to control center 102. In some embodiments, AR headset 400 displays the result of detection obtained from portable device 301. In some embodiments, AR headset 400 displays the streamed files, e.g., audio, video, location information, and current usage of the multi-functional wireless devices to the monitored personnel in real-time.

In some embodiments, third party 115 is capable of receiving the real-time streaming of files and recording the files through control center 102.

In some embodiments, AR headset 400 automatically captures the facial features of each inmate as the monitored personnel, wearing AR headset 400, passes the residential area, e.g., cell, of the inmate. AR headset 400 automatically performs a facial recognition of the facial feature of each inmate and obtains the information related to the identity of the inmate. For example, AR headset 400 automatically displays the information of the inmate upon the detection of the inmate's identity. In some embodiments, the information includes name, birthday, offense history, reasons for incarceration, and contact history of an inmate. Other information can also be displayed. In some embodiments, AR headset 400 captures the facial features of inmates through one or more of the front camera, the side cameras, and the rear camera. In some embodiments, AR headset 400 streams the captured images/videos to control center 102. In some embodiments, AR headset 400 streams the captured images/videos to third party 115 through control center 102. In some embodiments, AR headset 400 and/or control center 102 can monitor the inmates in real-time and/or record the streamed images/videos.

In some embodiments, multi-functional platform 101 further includes a wearable device that supplements the functions of portable device 301. FIG. 5 illustrates a block diagram 500 of a wearable device 501 containing certain functions to supplement certain functions of portable device 301. In some embodiments, wearable device 501 also includes AR functions. In an embodiment, wearable device 501 includes any suitable wearable devices being fixed onto the monitored personnel, such as a watch, a strap, and/or a band. Wearable device 501 is fixed at a position of the monitored personnel's body to more conveniently detect certain signals/data.

FIG. 6A illustrates a portion of a simulated map 600 reflecting certain status of subjects/objects in the area corresponding to the portion of map 600. Map 600 is simulated based on the signals/data provided by portable device 301, AR devices 211, and/or wearable device 501, with stored map data. Activities reflected by map 600 indicate real-time status of each subject/object detected by multi-functional platform 101. In some embodiments, map 600 is displayed at control center 102. In some embodiments, map 600 is also displayed on portable device 301, wearable device 501, and/or AR devices 211 carried by the monitored personnel.

As shown in FIG. 6A, the map shows the controlled environment includes an indoor environment and an outdoor environment. A portable device, same as or similar to portable device 301, is represented by element 601. The indoor environment contains cells 1-8, each being installed a positioning signal transmitter 603-n (n=1, 2, . . . , 8) in the cell. A positioning signal transmitter 603-n represents one or more transmitters of same or different types of positioning methods, e.g., Bluetooth, WiFi, RF, and/or ultrasound, where they can be installed in same or different positions in a cell. The positions of the transmitters allow signals transmitted by the transmitters to be sufficiently strong in a detectable distance range of a detecting devices, e.g., portable device 301 and/or AR headset 602. As shown in map 600, one inmate is positioned in cell 2, wearing an ID tag 603-22, another inmate is positioned in cell 3, wearing an ID tag 603-33, and another inmate is positioned in cell 7, wearing an ID tag 603-77. Inmate in cell 3 possesses a multi-functional wireless device 603-333. Inmate in cell 7 possesses a contraband wireless device 603-777. The monitored personnel is walking along the aisle for, e.g., a walk and observe assignment. In an embodiment, map 600 shows a designed path, the double-headed arrow, for the monitored personnel to follow. The area between the dashed lines is a permitted area to the monitored personnel, e.g., the monitored personnel is free to move in the area but is not permitted to go beyond the dashed lines. Element 604 represents any electronic device that can communicate with portable device 601.

In an embodiment, the monitored guard further wears an AR headset. The AR headset, same as or similar to AR headset 400, is represented by element 602. In some embodiments, AR headset 602 allows the monitored guard to simultaneously see front, side, and/or rear surroundings with augmented reality element. In an embodiment, the monitored personnel selects AR headset 602 to display front and rear views.

In an embodiment, a monitored personnel carries portable device 601 and AR headset 602 in an assignment. When the monitored personnel is in the indoor environment, portable device 601 automatically switches to “indoor mode,” and transmits detected signals/data to control center 102 (not shown in FIG. 6) in real-time. Positioning signal transmitters 603-n (n=1-8) includes WiFi access points transmitting known WiFi signals and other related parameters, e.g., MAC addresses, of the access points. Inmates in cells 2, 3, and 7 each wears an RFID, containing identification information of the inmates. Portable device 601 receives the WiFi signals and other parameters transmitted by nearby access points, transmits received WiFi signals and parameters to control center 102, and calculates the real-time location of portable device 601 based on the received WiFi signals and parameters, and pre-stored reference signal strength data of the WiFi signals. As the monitored personnel is moving, portable device 601 continuously sends received WiFi signals and parameters to control center 102 and calculates the real-time location of portable device 601. Portable device 601 further calculates moving speed, path, and/or dwelling times based on the positioning data. Results of the calculation are displayed on portable device 601.

Meanwhile, control center 102 similarly calculates the location, moving speed, path, and/or dwelling times based on received data. If an abnormal status is detected, e.g., monitored personnel moves beyond the permitted area, e.g., deviates from the designed path, both portable device 601 and control center 102 generate an alert, prompting the monitored personnel to respond within a certain period of time, e.g., one minute. In an embodiment, AR headset 602 displays the map, the simulated positioning information calculated by portable device 601, and augmented reality alert of “deviation from path” or the like as an overlay of the front view for the monitored personnel to see. The monitored personnel has the option to respond through portable device 601 or AR headset 602, e.g., by inputting text or voice. If the monitored personnel fails to respond within this period of time, portable device 601 starts streaming video to control center 102 and AR headset 602 displays an alert of “starting streaming of video” as an overlay of the front view. In another example, if portable device 601 is detected to be staying at one location or certain locations for an unexpected long period of time, portable device 601, AR headset 602, and/or control center 102 generate an alert, prompting the monitored personnel to respond within a certain period of time. In an embodiment, when the monitored personnel is detected to have deviated from the designed path, portable device 601 automatically starts recording video and streaming the recorded video to control center 102. In some embodiments, when the monitored personnel is detected to have deviated from the designed path, AR headset 602 automatically starts streaming the front view and the rear view to control center 102. In another embodiment, control center 102 controls portable device 601 and a wearable device same as or similar to wearable device 501 to both start recording and streaming videos when the monitored personnel is detected to have deviated from the designed path.

In another embodiment, portable device 601 detects and counts the presence of inmates in the detectable distance range. Portable device 601 reads out identification information transmitted by the ID tags, e.g., RFID tags 603-22, 603-33, and 603-77, carried by the inmates, and sends the identification information to control center 102. Control center 102 compares the identification and location information with pre-stored inmate data and determines whether the presence information matches pre-stored inmate data. If a mismatch is found, e.g., inmate absent or inmate in the wrong cell, control center 102 send an alert to portable device 601, prompting the monitored personnel to check and confirm. If the monitored personnel fails to respond within a certain period of time or confirms absence, control center 102 sends an alert to other monitored personnel carrying portable devices 601 and/or other personnel. In an embodiment, ID tags 603-22, 603-33, and 603-77 also contain Bluetooth beacons. Portable device 601 detects the location and moving of inmates carrying the ID tags based on received Bluetooth signals. In an example, when portable device 601 detects an inmate is moving towards the monitored personnel at an unusually high speed, portable device 601 alerts the monitored personnel. The monitored personnel has the option to respond to such situation by notifying control center 102 and/or other personnel. In various embodiments, positioning information of inmates are also sent to control center 102 through communication device for further processing and calculation.

In an embodiment, ID tags, e.g., 603-22, 603-33, and 603-77, contain the criminal and/or violation history of corresponding inmates, which is also stored in control center 102. When an inmate having a history of aggression or malicious behavior, e.g., being malicious towards personnel in the controlled environment, is detected to be in the proximity of the monitored personnel, portable device 601 or control center 102 sends an alert to the monitored personnel, notifying him/her the presence of such inmate.

In an embodiment, portable device 601 detects an unknown wireless signal 603-777 within the detectable distance range, e.g., transmitted from a contraband wireless device in cell 7. The unknown signal 603-777, corresponding location, and/or corresponding inmate information are thus detected by portable device 601 and control center 102. Control center 102 further starts investigation of the contraband wireless device.

In an embodiment, when the monitored personnel undergoes a sudden body motion or sudden heart rate increase/decrease, portable device 601 sends an alert to control center 102 and starts streaming video. In various embodiments, the monitored personnel has the option to initiate communication, e.g., texting or video chatting, sending images and voice messages, and/or record images and videos during an assignment. The monitored personnel also has the option to start streaming videos at a desired time.

In an embodiment, portable device 601 includes voice control functions. A voice sample of the monitored personnel is stored and registered in communication system 100 for authenticate the monitored personnel's identity. The monitored personnel has the option to activate certain functions of portable device 601 using his/her voice and/or certain phrases. In some embodiments, a portable device 601 can only be voice controlled by the monitored personnel assigned to portable device 601.

In an embodiment, wireless device 604 communicates with portable device 601 by sending related information, e.g., type, manufacturer, usage, operation status, etc. In some embodiments, wireless device 604 is controlled by control center 102 and/or portable device 601. The monitored personnel and/or control center 102 have the option to remotely control certain functions of wireless device 604, e.g., recording of videos, sending location of wireless device 604 to portable device 601/control center 102, and so on. The availability of functions are dependent on the type of wireless device 604 and should not be limited by the embodiments of the present disclosure.

In an embodiment, when the monitored personnel enters the outdoor environment, portable device 601 directly switches to the “outdoor mode,” and starts sending GPS coordinates to control center 102 in real-time. Meanwhile, portable device 601 calculates positioning information using GPS coordinates and updates the positioning information on the map.

In various embodiments, the monitored personnel also wears a wearable device (not shown in FIG. 6A) same as or similar to wearable device 501 illustrated in FIG. 5. The operation of the wearable device is similar to portable device 601. In some embodiments, portable device 601 receives heart rate data and body motion data of the monitored personnel from wearable device and sends the data to control center 102. For example, when guard undergoes a sudden acceleration or movement, e.g., falling on the floor, the wearable device and/or portable device 601 detect such abnormal activity and send an alert to control center 102. In some embodiments, the recording/streaming functions of portable device 601 and the wearable device can be used separately. That is, the monitored personnel has the option to use portable device 601 and the wearable device at same time for recording/streaming different scenes, or use portable device 601 and wearable device at different times. Control center 102 has the authority to control the operation of portable device 601 and wearable device.

In some embodiments, the wearable device includes only certain functions of portable device 601 to supplement portable device 601. Accordingly, the wearable device has reduced volume and size, and is easier to wear. For example, the wearable device may only have the heart rate and body motion monitoring function and data transmission function. Detected heart rate and body motion data is sent to portable device 601 and/or control center 102 for processing and analysis. In some embodiments, portable device 601 and the wearable device have complementary functions.

In an embodiment, AR headset 602 is configured to detect nearby inmates, similar to portable device 601, and perform facial recognition of inmates captured in the camera. AR headset 602 displays augmented reality element of the recognized inmates upon the detection of the inmates. In an embodiment, AR headset 602 displays information of inmates as augmented reality data when the monitored personnel passes the inmates' assigned locations. In some embodiments, at least some functions performed by AR headset 602 overlap with the functions performed by portable device 601.

Depending on different applications and design preferences, communication system 100, including control center 102, portable device 601, AR headset 602, and wearable device are configured to respond to different situations differently. In various embodiments, portable device 601, AR headset 602, and the wearable device are configured to have complementary functions in response to various situations. The combination of situations and responses should be subjected to designs and preferences of different applications and should not be limited by the embodiments of the present disclosure.

FIG. 6B illustrates exemplary front and rear views displayed by AR headset 400. In an example, AR headset 400 arranges the front view 607 on top of rear view 608 for ease of viewing by the monitored personnel. In an embodiment, in the front view 607, the monitored personnel sees the inmate cells 2-4 and 6-8 through AR headset 400. AR headset 400 displays augmented reality element, e.g., ID tags 603-22, 603-33, and 603-77 in cells 2, 3, and 7, respectively, to inform the monitored personnel the presence of corresponding inmates. AR headset 400 also displays augmented reality element showing existence of contraband electronic device 603-777 in cell 7 and multi-functional wireless device 603-333 in cell 3. AR headset 400 further displays augmented reality element of the boundary of the permitted area (dashed lines) and permitted direction of moving.
